Presenter’s Notes:

The fluvial domain was analyzed using the Flow-Zone-Indicator Methodology (FZI). It has been possible to identify three different populations in the LOG FZI chart (three different FLOW UNITS [of reservoir quality]). The worst, P1, is more abundant and has a high proportion of authigenic minerals (mainly smectite). The best one, P3, is the least common, showing the least amount of authigenic clays (mainly mechanically infiltrated smectite that probably has preserved some depositional characteristics).
